Ionized magnesium in erythrocytes--the best magnesium parameter to observe hypo- or hypermagnesemia.

BACKGROUND Almost 99% of the body magnesium is inside cells. The concentration of intracellular ionized magnesium (iMg) is physiologically relevant. iMg in erythrocytes is a new parameter that can help to establish reliable information on the functional magnesium status. METHODS iMg concentration in erythrocytes and serum was measured by ion-selective… (More)
